TURBINE.

To all, HIt-Olll it may eoneem:

tie it known that [(lthx lL-uannntnru, a eitizen of the Empire ofGennany. residing in New York, borough ot' Munlmttnn. in the eouuty andState of New York, have invenhrd eertuin new and useful Improvethin.

This invention relates to improvements in radial in ward-How reactionturbines and is intended to equalize the different pressures at anymoment in the spnees between the lllllliti'( 'l'0\\'llfi and 'inelosingcasing or heads of the turbine.

in radial inu'urd-tlow' reaction turbines a certain quantity ol' waterpasses through the narrow annular spaces between the circunil'erentizilflanges of the runner and the casing of the turbin into the spaces. atboth sides of the runner between the runner-and casing, and producesthereby unere'n pressures on both sides of the runner. whereby an endthrust on the shaft is ereated.

The object of this invention is to obviate these un even pressi'ires andto minimize the pressure on the thrust-lu-aring, so as to preventtheheating and burning oi" tlielnttcr; and for this purpose the invention(:unsistsml' n. rudiul innzil'ddluW reaction turbine in which therunner-vanes Zll'( provided with transverse openings or ehunnels intheir outer ends by which the water t'al-ii freely pass from the spacelocated between the runner-bottom and the lie-lid of the turbine at oneside-oi the runner to the spaee hotwedn therunner and easing at theopposite side oi'therinnier.

The shaft is rotnted in suitabljourtml-lu-arings and provided at one end with :l. thrust-ln-uring (Ifor titkieg up the thrust exerted by the runner on its shnl'ti 'lhe huhoi' the :runner is keyed to-un enlarged seetion ot' the shn-l't h. undthe web or-bolloin ol' the runner provided near the shztl'ti withinclined openings or chunnels o lhroiiglrwhieh t'he water pusses fromthe space between the runnerand tho outer head of the casing to thesuction-pipe g.

while the water which passes into the opposite space 0 passes throughthe inclined openings 0 in the runnerbottom. Owing to the difference inthe size oi the spaces or chambers and their arrangement, to thedifference .in the leakage, and to the difference in the centrifugalaction of the water in thotwo chambers, it is impossible in practice tohave a uniform pressure in the chambers.

As all the vanes areprovidul with transverse channels. illl(l tl-Sthereby :1, large number of connections between the ,spaees'c, c, inaddition to the inclined ehannels o, are supplied. the pressures in thespaces 6, a are equalized; so that; n more uniforinmotion of the runner,without pressure on the thrust-bearing, is
